BACKGROUND

With the advent of more robust wireless communications systems,compatible handheld communication devices are becoming more prevalent,as well as advanced. In a broader sense, these devices are referred toas handheld electronic devices, which include devices withoutcommunication functions. Where in the past such handheld communicationdevices typically accommodated either voice (cell phones) or texttransmission (pagers and PDAs), today's consumer often demands acombination device capable of performing both types of transmissions,including sending and receiving e-mail. Furthermore, these devices arecapable of sending and receiving other types of data including data toenable the listening of audio, and viewing of websites, and still andmoving images. The suppliers of such mobile communication devices andunderlying service providers are anxious to meet these demands, but thecombination of voice and textual messaging, as well as otherfunctionalities such as those found in PDAs, have caused designers tohave to improve the functionality as related to viewing and editing ofdocuments and other data on these electronic devices.

In recent years, the use of touch sensitive screens on electronicdevices has become common. These touch sensitive screens generallyrespond to any touching including the use of a stylus and a human digit.Depending on the size of the device and screen, the need for accuratecontrol can be appreciated. Some icons or selectable objects presentedon the screen are large in order to enable the user to accurately selectthe individual icon or selectable object, while other views such as textdisplayed on the screen require greater accuracy in the selection of theitems. As the size of the display screen decreases, the need foraccurate placement of the cursor can be accentuated. This need foraccuracy is amplified when both the screen of the device and thedisplayed text are small. The typical solution for accurate placementinvolves using a stylus to select a point on the screen. Since the tipof the stylus is typically of similar size to the text shown on thedisplay screen, accurate selection of the appropriate point is possible.

However, there are instances where a stylus is not desirable or isunavailable. Typically, the electronic device is provided with a meansfor holding or storing the stylus when the stylus is not in use. Thus ifaccurate selection is required, the user must remove the stylus fromstorage before making a selection on the screen. Furthermore, the styluscan be lost by the user. A device with a stylus is larger due to thestylus and its storage requirements. The additional space required forstorage of the stylus is often not desirable. Thus, another solution toaccurately select a point is needed.

DETAILED DESCRIPTION

An exemplary handheld electronic device 300 is shown in FIG. 1, and thedevice's cooperation in a wireless network 319 is exemplified in theblock diagram of FIG. 21. These figures are exemplary only, and thosepersons skilled in the art will appreciate the additional elements andmodifications necessary to make the device 300 work in particularnetwork environments.

The block diagram of FIG. 21 denotes the device's 300 inclusion of amicroprocessor 338 that controls the operation of the device 300. Acommunication subsystem 311 performs all communication transmission andreception with the wireless network 319. The microprocessor 338 furtherconnects with an auxiliary input/output (I/O) subsystem 328, a serialport (preferably a Universal Serial Bus port) 330, a display 322, akeyboard 332, a speaker 334, a microphone 336, random access memory(RAM) 326, and flash memory 324. Other communication subsystems 340 andother device subsystems 342 are generally indicated as beingfunctionally connected with the microprocessor 338 as well. An exampleof a communication subsystem 340 is that of a short range communicationsystem such as BLUETOOTH® communication module or a Wi-Fi communicationmodule (a communication module in compliance with IEEE 802.11b) andassociated circuits and components. Additionally, the microprocessor 338is able to perform operating system functions and preferably enablesexecution of software applications on the communication device 300.

The included auxiliary I/O subsystem 328 can take the form of a varietyof different navigation tools (multidirectional or single-directional)such as a trackball navigation tool 321 as illustrated in the exemplaryembodiment shown in FIG. 1, or a thumbwheel, a navigation pad, or ajoystick, or the like. These navigation tools are preferably located onthe front surface of the device 300 but may be located on any exteriorsurface of the device 300. Other auxiliary I/O subsystems 328 caninclude external display devices and externally connected keyboards (notshown). While the above examples have been provided in relation to theauxiliary I/O subsystem 328, other subsystems capable of providing inputor receiving output from the handheld electronic device 300 areconsidered within the scope of this disclosure. Additionally, other keysmay be placed along the side of the device 300 to function as escapekeys, volume control keys, scrolling keys, power switches, or userprogrammable keys, and may likewise be programmed accordingly.

As may be appreciated from FIG. 1, the handheld communication device 300comprises a lighted display 322 located above a keyboard 332constituting a user input and suitable for accommodating textual inputto the handheld communication device 300. The front face of the devicehas a keyfield 650 that includes menu keys 652, alphanumeric keys 630,alphabetic keys 632, numeric keys 42, and other function keys as shownin FIG. 1. As shown, the handheld device 300 is of unibody construction,also known as a “candy-bar” design.

Keys, typically of a push-button or push-pad nature, perform well asdata entry devices but present problems to the user when they must alsobe used to affect navigational control over a screen-cursor. In order tosolve this problem the present handheld electronic device 300 preferablyincludes an auxiliary input 328 that acts as a cursor navigational tooland which is also exteriorly located upon the front face of the device300. Its front face location is particularly advantageous because itmakes the tool easily thumb-actuable like the keys of the keyboard. In aparticularly useful embodiment, the navigational tool is a trackballnavigational tool 321 which is easily utilized to instructtwo-dimensional screen cursor movement in substantially any direction,as well as act as an actuator when the ball 321 is depressed like abutton. The placement of the trackball 321 is preferably above thekeyboard 332 and below the display screen 322; here, it avoidsinterference during keyboarding and does not block the user's view ofthe display screen 322 during use. (See FIG. 1).

As illustrated in at least FIG. 1, the present disclosure is directed toa handheld electronic device 300 configured to send and receive textmessages. The device includes a hand cradleable body configured to beheld in one hand by an operator of the device during text entry. Adisplay 322 is included that is located on a front face 370 of the bodyand upon which information is displayed to the operator during textentry. A key field 650 is also located on the front face 370 of theelongate body and which comprises a plurality of keys including aplurality of alphanumeric keys, symbol keys, and function keys. Atrackball navigation tool 321 is also located on the front face 370 ofthe body. The alphanumeric input keys comprise a plurality of alphabetickeys 632 having letters associated therewith. The order of the lettersof the alphabetic keys 632 on the presently disclosed device can bedescribed as being of a traditional, but non-ITU Standard E.161 layout.

The handheld electronic device 300 is also configured to send andreceive voice communications such as mobile telephone calls. At leastone key of the key field 650 is positioned adjacent to the trackballnavigation tool and that key has a circular arc-shaped edge conformancefitting to a circular arc-shaped boundary about the trackball navigationtool 321. To facilitate telephone calls, two call keys 605, 609oppositely and laterally flank the trackball navigation tool. One of thetwo call keys is a call initiation key 605 and the other is a calltermination key 609.

The key 606 positioned adjacent to the trackball navigation tool 321 isa menu key that upon actuation displays an available action menu on thedisplay in dependence of the currently running application on the device300. Additionally, an escape or back key 608 can be provided. As shown,the back key 608 is located on the opposite side of the trackballnavigation tool 321.

Furthermore, the device is equipped with components to enable operationof various programs, as shown in FIG. 21. In an exemplary embodiment,the flash memory 324 is enabled to provide a storage location for theoperating system, device programs 358, and data. The operating system isgenerally configured to manage other application programs 358 that arealso stored in memory 324 and executable on the processor 338. Theoperating system honors requests for services made by applicationprograms 358 through predefined application program 358 interfaces. Morespecifically, the operating system typically determines the order inwhich multiple applications 358 executed on the processor 338 and theexecution time allotted for each application 358, manages the sharing ofmemory 324 among multiple applications 358, handles input and output toand from other device subsystems 342, and so on. In addition, users cantypically interact directly with the operating system through a userinterface usually including the keyboard 332 and display screen 322.While in an exemplary embodiment the operating system is stored in flashmemory 324, the operating system in other embodiments is stored inread-only memory (ROM) or similar storage element (not shown). As thoseskilled in the art will appreciate, the operating system, deviceapplication 358 or parts thereof may be loaded in RAM 326 or othervolatile memory.

In one exemplary embodiment, the flash memory 324 containsprograms/applications 358 for execution on the device 300 including anaddress book 352, a personal information manager (PIM) 354, and thedevice state 350. Furthermore, programs 358 and other information 356including data can be segregated upon storage in the flash memory 324 ofthe device 300.

When the device 300 is enabled for two-way communication within thewireless communication network 319, it can send and receive signals froma mobile communication service. Examples of communication systemsenabled for two-way communication include, but are not limited to, theGeneral Packet Radio Service (GPRS) network, the Universal MobileTelecommunication Service (UTMS) network, the Enhanced Data for GlobalEvolution (EDGE) network, and the Code Division Multiple Access (CDMA)network and those networks, generally described as packet-switched,narrowband, data-only technologies which are mainly used for short burstwireless data transfer. For the systems listed above, the communicationdevice 300 must be properly enabled to transmit and receive signals fromthe communication network 319. Other systems may not require suchidentifying information. GPRS, UMTS, and EDGE require the use of aSubscriber Identity Module (SIM) in order to allow communication withthe communication network 319. Likewise, most CDMA systems require theuse of a Removable Identity Module (RUIM) in order to communicate withthe CDMA network. The RUIM and SIM card can be used in multipledifferent communication devices 300. The communication device 300 may beable to operate some features without a SIM/RUIM card, but it will notbe able to communicate with the network 319. A SIM/RUIM interface 344located within the device 300 allows for removal or insertion of aSIM/RUIM card (not shown). The SIM/RUIM card features memory and holdskey configurations 351, and other information 353 such as identificationand subscriber related information. With a properly enabledcommunication device 300, two-way communication between thecommunication device 300 and communication network 319 is possible.

If the communication device 300 is enabled as described above or thecommunication network 319 does not require such enablement, the two-waycommunication enabled device 300 is able to both transmit and receiveinformation from the communication network 319. The transfer ofcommunication can be from the device 300 or to the device 300. In orderto communicate with the communication network 319, the device 300 in thepresently described exemplary embodiment is equipped with an integral orinternal antenna 318 for transmitting signals to the communicationnetwork 319. Likewise the communication device 300 in the presentlydescribed exemplary embodiment is equipped with another antenna 316 forreceiving communication from the communication network 319. Theseantennae (316, 318) in another exemplary embodiment are combined into asingle antenna (not shown). As one skilled in the art would appreciate,the antenna or antennae (316, 318) in another embodiment are externallymounted on the device 300.

When equipped for two-way communication, the communication device 300features a communication subsystem 311. As is well known in the art,this communication subsystem 311 is modified so that it can support theoperational needs of the device 300. The subsystem 311 includes atransmitter 314 and receiver 312 including the associated antenna orantennae (316, 318) as described above, local oscillators (LOs) 313, anda processing module 320 which in the presently described exemplaryembodiment is a digital signal processor (DSP) 320.

It is contemplated that communication by the device 300 with thewireless network 319 can be any type of communication that both thewireless network 319 and device 300 are enabled to transmit, receive andprocess. In general, these can be classified as voice and data. Voicecommunication is communication in which signals for audible sounds aretransmitted by the device 300 through the communication network 319.Data is all other types of communication that the device 300 is capableof performing within the constraints of the wireless network 319.

Example device applications that can depend on such data include email,contacts and calendars. For each such application synchronization withhome-based versions on the applications can be critical for either orboth of their long term and short term utility. As an example, emailsare often time sensitive, so substantially real time synchronization ishighly desirable. Contacts, on the other hand, can be usually updatedless frequently without inconvenience. Therefore, the utility of thedevice 300 is significantly enhanced (if not enabled) when connectablewithin a communication system, and particularly when connectable on awireless basis in a network 319 in which voice, text messaging, andother data transfer are accommodated.

Integration of the trackball assembly into handheld device 300 can beseen in the exploded view of FIG. 13 showing some of the typicalcomponents found in the assembly of the handheld electronic device 300.The construction of the device benefits from various manufacturingsimplifications. The internal components are predominantly constructedon a single PCB (printed circuit board) 102. The keyboard 332 can beconstructed from a single piece of material, and in some embodiments ismade from plastic. The keyboard 332 sits over dome switches (not shown)located on the PCB 102 in a preferred embodiment. While in the presentlydescribed exemplary embodiment one switch is provided for every key onthe keyboard 332, in other embodiments more than one switch or less thanone switch per key are provided. The support frame 101 holds thekeyboard 332 and trackball navigation tool 321 in place above the PCB102. A lens 103 covers the display screen (not shown) to prevent damage.When assembled, the support frame 11 and the PCB 102 are fixablyattached to each other and the display is positioned between the PCB 102and support frame 101.

The trackball navigation tool 321 can be frictionally engaged with thesupport frame 101, but in one exemplary embodiment the trackballnavigation tool 321 is removable when the device is assembled. Thisallows for replacement of the trackball navigation tool 321 if/when itbecomes damaged or the user desires replacement with a different type ofnavigation tool. Other multidirectional navigation tools such asjoysticks, four-way cursors, or touch pads are also considered to bewithin the scope of this disclosure. The trackball navigational tool 321is fixed against the support frame 101 by locking rings 122, 123 thatare removably engaged with the support frame. This configuration allowsthe trackball navigational tool 321 to be removed such as needed inservicing or replacement.

A serial port (preferably a Universal Serial Bus port) 330 and anearphone jack 140 are fixably attached to the PCB 102 and further heldin place by right side element 105. Buttons 130-133 are attached toswitches (not shown), which are connected to the PCB 102.

Final assembly involves placing the top piece 107 and bottom piece 108in contact with support frame 101. Furthermore, the assemblyinterconnects right side element 105 and left side element 106 with thesupport frame 101, PCB 102, and lens 103. These side elements 105, 106provide additional protection and strength to the support structure ofthe device 300. In a preferred embodiment, backplate 104 is removablyattached to the other elements of the device.

The above mentioned elements can be combined with the present solutionswhich are directed to methods and arrangements for accommodatingcharacter or text selection.

An exemplary method for accommodating character or text selection isillustrated in FIG. 11. While the figure illustrates the method ascontinuous, the method can be stepwise or segmented as described below.Furthermore, implementations of only a portion of the method illustratedare considered within the scope of this disclosure.

In a preferred embodiment, a method displays selectable text on a touchscreen 322 of the handheld electronic device 300 in which the selectablecharacters are smaller than an area of user contact with the touchscreen. When a finger of the user is used in making the selection, theuser contact with the touch screen 322 is on the order of the size ofthe fingertip of the user. When the fingertip is used for making aselection, at least two characters are partially covered by the area ofuser contact which prevents accurate selection of the desired character.This display configuration in which the selectable characters aresmaller than the area of user contact is referred to as an originaldisplay configuration (block 501). Also, the method involves detectingthat a first area of the touch screen 322 has been contacted by the user(block 502). The first area usually includes a plurality of charactersdue to the overlap of characters. Additionally, the method displays anexpanded view of the first area that has been expanded to an extent thateach of the at least two partially covered characters is individuallysufficiently large that only one of said at least two characters can bepredominantly covered by the area of user contact (block 503).Furthermore, the method detects that a first character is beinguser-contacted in the first expanded view by being predominantlyuser-contacted in the expanded view (block 504). Preferably, the firstcharacter is selected from the at least two characters. A character thatis predominantly user-contacted is a character that has moreuser-contact than any other character shown on the display. The originaldisplay configuration is resumed with the first character being visuallysignified (block 505).

In an exemplary embodiment, the method for accommodating character ortext selection also detects a second area encompassing a plurality ofcharacters of which at least two have been at least partially covered byuser-contact (block 506). Furthermore, the method displays a secondexpanded view of an area corresponding to the second area (block 507),and each of the plurality of characters being individually sufficientlylarge in the expanded view such that only one of said at least twocharacters can be predominantly covered by the user-contact.Additionally, the method involves detecting a second character that wasuser-contacted in the expanded view by being predominantly covered byuser-contact (block 508) and resuming the original display configurationof the text with the text between the first character and said secondcharacter being visually signified as designated text (block 509).

In another embodiment, the method for accommodating character or textselection further involves detecting that a third area of the touchscreen 322 has been user-contacted (block 510). The user-contact is thendragged across the touch screen 322 to a third location where a thirdarea is defined by the user-contact. This third area encompasses aplurality of characters of which at least two have been at leastpartially covered by the user's contact. Then, the method detects adragging motion of the user-contact across the screen followed byremoval of the user-contact (block 511). Additionally, the methoddisplays an expanded view of the third area upon detection that theengaging user-contact has disengaged from the touch screen (block 511).The third expanded view has been expanded to an extent that each of theat least two partially covered characters in the expanded view isindividually sufficiently large that only one of said at least twocharacters can be predominantly covered by the user's contact.Furthermore, the method detects a third character that has beenuser-selected (block 513) in the third expanded view (block 512) andinserts the designated text adjacent the third character (block 514),and resumes the original display configuration (block 515). Aspreviously mentioned, the text shown in the original displayconfiguration of the device 300 is sized such that a user's contactoverlaps more than one character of the displayed text.

While generally the engagement is generally described as user contact,the specific example of a fingertip is provided below as anillustration. However, other examples of objects that can be used tocause solid contact include at least a pen, pencil, stylus, eraser,finger, knuckle, fingernail, thumbnail, or other similar object.

Characters can be anything commonly displayed in the text field of ahandheld electronic device 300. Characters include, but are not limitedto letters, numerals, spaces, punctuation, and symbols. Typically, thetext shown on the touch screen 322 of the electronic device 300 is sizedsuch that it is small enough to allow multiple lines of text to be shownat the same time enabling the user to easily read the displayed text.The original display configuration is also the default view of thedevice. This default view of the device can be either preset or userdefinable. If the view is user definable, the user is allowed to adjustthe amount of information shown on the screen 322 through adjustment ofthe font size or the like. Typically more than three lines of text aredisplayed while in the original display configuration. Preferably, thenumber of lines of text shown on the screen 322 varies from four tofifteen lines of text.

While the original display configuration provides several lines of textfor viewing on the screen 322, the expanded view provides fewer lines oftext and/or fewer characters. The expanded view can be describedgenerically and likewise the description of the expanded view coversfirst, second, and third expanded views, as used herein. In oneembodiment, the expanded view has less than four lines of text displayedon the screen 322 when the expanded view is enabled. In anotherembodiment, the line of the selected area and one line above and oneline below the selected area are shown on the screen 322 when in theexpanded view in FIG. 3. Thus, the three lines shown in the expandedview are likely to contain the text or character that the user intendedon selecting. Alternatively, the text shown on the display 322 isdefined in terms of the characters on the adjacent sides of the selectedarea. Preferably, the number of characters on either side of theselected character is less than six characters. In an exemplaryembodiment, the number of characters adjacent to the selected area is onthe order of four to ten. In yet another embodiment, the expanded viewcan be described as having characters that are individually sufficientlylarge that only one of the at least two characters can be predominantlycovered by the user's fingertip. Exemplarily, the height of a characteris slightly larger than the average size of a human fingertip. Acharacter with a height greater than six millimeters is one example ofcharacter that would meet this requirement. Preferably, the characterheight is between six and fourteen millimeters. Alternatively, the widthmay be specified as between four and fourteen millimeters, andpreferably the width is approximately six millimeters. The abovedescribed expanded views preferably retain the aspect ratios of thedisplay screen 322, such that the text shown on the display 322 meetsthe above criteria and has additional text as required to complete theview. In yet another embodiment, the expanded view can be defined as amagnification of the original display configuration. Using the selectedarea as the center point of the expanded view, the remaining text isscaled at a predefined percentage. Preferably, the percentage ofmagnification of the expanded view as compared with the original view ison the order of two hundred to four hundred percent.

While the above has been described generally as a method foraccommodating character or text selection, the method is preferablyimplemented in a software routine or other known programming techniquefor a handheld electronic device 300. For example, a microprocessor-runsoftware program can be provided on the handheld electronic device 300.

As previously described, the method and apparatus for accommodatingcharacter or text selection can be further understood in relation toFIGS. 1-10. As shown in FIG. 1, the handheld electronic device 300 iscradled in the palm of a user's hand. The handheld electronic device 300is preferably provided with a keyboard 332 to enter text data and placetelephone calls. A connect/send key 605 is preferably provided to aid inthe placement of a phone call. Additionally, a disconnect/end key 609 isprovided. The send key 605 and end key 609 preferably are arranged inrow of keys including a trackball navigation tool 321. Additionally, therow of keys with the navigation tool preferably has a menu key 606 andan escape key 608 associated therewith. The menu key 606 is used tobring up a menu and the escape key 608 is used to return to the previousscreen or previous menu selection. The original display configuration isshown on the touch sensitive screen 322. The text shown on the screen322 is provided for illustrative purposes only. In other embodiments,the display 322 includes additional headings, frames, and otherorganization characteristics not shown in the figure. Thus, the textthat is selectable in the original display configuration may not occupythe entire screen 322. As can be seen in FIG. 2, the size of the text issmaller than the user contact such as fingertip of the user. While thedescription below, for illustrative purposes, refers to finger tipengagement of the screen 322, other user contact is likewise applicable.Using touch screen technology, the characters of the text shown on thetouch screen 322 are selectable. However, the size of the user'sfingertip is larger than a character on the display 322. Thus, whenselecting a character on the display 322, there is possible overlap withadjacent characters.

The user of a handheld electronic device 300 often wishes to edit textby selecting blocks of text. Although not described in detail in thisdisclosure, various implementations are possible for enablingmanipulation of text. Some examples of manipulation of text are givenherein as examples. One type of manipulation involves copying theselected text. This can be performed through a variety of ways, usuallywith the user selecting a copy operation. Alternatively, the selectionof text is made and subsequently the user indicates the use of theselected text. This can be through a series of keystroke commands orthrough selection of menu items on a graphical user interface shown onthe display screen 322. Once the text is selected that will be copied, apoint for insertion of the text is required. With a specified insertionpoint, the text is inserted at that point. Likewise, cut and deleteoptions are possible. The cut operation involves deleting the selectedtext from its original position, once the insertion point is determined,and inserting the text at the selected point. The delete option is usedto delete the entirety of the selected text. Other options formanipulating the selected text are possible as well. The above examplesprovide some illustration as to how selected text might be used. Thus,while this disclosure generally describes the manipulation of text as itrelates to a cut operation, it can be understood how modifications canbe made to implement copy and delete operations. In addition to menuselection of the above text manipulation functions, it is also possibleto design the touch sensitive screen 322 to accept gestures forinputting of the commands. The gestures involve placing one or morefingers of the user on the touch screen 322 and moving the fingers indesignated fashion to input commands.

When a user desires to select a block of text, an endpoint for the blockis usually determined. As shown in FIG. 2, the user touches 21 thescreen 322 of the handheld electronic device 300 in order to indicate adesired point. This point preferably is used in determining theselection of text. Since the area selected by the user does not coincidewith just one character because of the overlap of characters around thearea, an additional selection of the desired character is required.

As shown in FIG. 3, a first expanded view is generated on the screen322. The characters in the expanded view are individually sufficientlylarge such that they can be touch-selected by the user with onecharacter being predominantly fingertip-covered. The character 35 thatthe program has selected as the most likely character selected by theuser based upon the first touch 21 is visually signified 30. This visualsignification can be, for example, a background highlighting color (asshown) or a different font color for the character or other method tosignify to the user that the character is selected. Then, the userselects 22 the desired character, as shown in FIG. 4. The implementationrequires detecting this selection in the first expanded view and usingthis selection as one desired endpoint for the text selection. Eventhough the above is described in relation to text selection, theselection can be used for selection of other things such as graphics orother objects. The use of the expanded view allows for a furtherrefinement of initial selection to provide increased accuracy in theselection of a desired point on the screen 322. Once the first characterhas been detected, the screen 322 resumes the original displayconfiguration with the first character visually signified, as shown inFIG. 5.

While in some embodiments the mere selection of a character is all thatis desired, other embodiments further involve selecting a block of text.As continued from the above described circumstance, a second endpoint ofthe text is selected. This involves a similar process as previouslydescribed. As shown in FIG. 5, the original display configuration isshown on the screen 322 and the previously selected character 36 ishighlighted by a cursor 30. The user indicates the desire to selectanother endpoint through selection of a second area on the touch screen322 through fingertip-engagement 23. Then, a second expanded view, shownin FIG. 6, is displayed on the screen 322 in which the characters areindividually sufficiently large, as previously discussed above. The userfurther refines the previous character selection 37, indicated by cursor32, by touching the screen 322 at an area 24 corresponding to thedesired character. This second character is detected. Then the originaldisplay configuration is shown on the screen 322 with the text betweenthe first character and the second character being visually signified 38as designated text, as shown in FIG. 7. The visual signification of thetext between the two characters can be as described previously.Preferably, this text is visually signified by applying backgroundshading to the text.

The selected text can then be inserted at a third point. The fingerselects the visually signified text by placing the finger over thatarea, such that it contacts a portion of the selected text, and dragsthe text to a third point for insertion. As shown in FIG. 8, when thefinger comes to a stop and is removed at a third area 25, an initialpoint for insertion is specified. Alternatively, a third area 25 istouched on the screen 322 of the device 300. Once the third area isspecified, a third expanded view, as shown in FIG. 9, is shown on thescreen 322 to allow further refinement of the selected area. Then, thetouch screen 322 detects that a third character, in this case a blankspace, has been fingertip-selected 26. As can be seen in FIG. 10, theselected text 70 is then inserted at the space adjacent to the thirdcharacter 26 and the original display configuration is resumed 501.

In another embodiment as shown in FIG. 12, the method for character ortext selection can be described as follows. While the screen 322 isdisplaying text in an ordinary configuration as described above, a firsttouch on the touch sensitive screen 322 is detected (block 550). Next, azoom view is implemented in which the area around the first touch iscentered on the display 322 and corresponding text is magnified suchthat the text shown on the display 322 is larger than the originaldisplay configuration (block 552). Then, a second touch is detected onthe screen 322 (block 554). Once the second touch is detected, thescreen 322 resumes the original display configuration by zooming out tothis standard configuration (block 556). In the original displayconfiguration, a cursor or other visual indicator is shown at the secondtouch point (block 558). If the user desired only single characterselection, this could be provided through the above provided steps.However if further selection of text is desired, a third touch can bedetected on the touch sensitive screen 322 of the device 300 (block560). Once the third touch is detected, the area surrounding the thirdtouch is magnified to show the text around the third point in largerfont size (block 562). Next, a fourth touch is detected (block 564) anddisplay configuration is zoomed out to show the original displayconfiguration (block 566). When the text is shown in the originaldisplay configuration, the text appearing between the second and fourthtouch is visually signified through one of the above described ways,including a different background (block 568). If further manipulation ofthe text is required, such as pasting, then a fifth touch can bedetected (block 570). Then a dragging motion is detected across thedisplay screen 322 (block 571), followed by a release of the finger(block 572). As previously described in relation to other detections,the area around the finger release is magnified (block 573). At thispoint, a sixth touch by the user is detected (block 574). Finally, thedisplay 322 resumes the original display configuration (block 576) andthe visually signified text is inserted at the sixth point (block 578).

While the above disclosure generally references the selection ofcharacters and text as occurring continuously, other embodiments areconsidered which provide for only portions or segments of the abovedescribed selection and placement of characters or text. Furthermore,the user may be required to enter commands or make menu selections inorder to implement the above described character or text manipulation.For example, the user may have to indicate the desire to make aselection by selecting an item from a menu designating characterselection. Alternatively, the selection of the text or characters can bemade without interaction with a menu, but once the selection is made, amenu selection is required to perform a cut or delete operation on theselected text. Additionally, when inserting the text, a user might berequired to select a paste or insert operation from a menu once aninsertion point has been specified. Alternatively, the user could selectpaste and be prompted to select the insertion point. While the above hasdescribed the interaction with a program as being through menu selectionfeatures, short cut commands that replace the menu selection are alsoconsidered within this disclosure. Additionally, gestures may beimplemented to enable the text selection and manipulation options.

While a user may complete the text selection process without anyproblems, other embodiments are considered that allow the user to escapeor exit a particular selection. If the user did not like the characterselection made, a command key or menu selection can be made to rejectthe selection. The rejection of the selection can be limited to theprevious selection or all selections prior to the decision by the userto reject the selection. These are similar to the well known undo orredo options available in computer programs.

The above described methods and apparatus can combine with the followingmentioned elements as one of the ordinary skill in the art mayappreciate. Although the method and apparatus has been described inrelation to selection of text, the method and apparatus may beimplemented to edit and manipulate other objects shown on the screen ofthe device such as images. In another embodiment, the manipulation ofthe text is afford through a microprocessor-run software program for ahandheld electronic device configured for displaying characters for userselection. The displayed characters are small enough that user contactwith the touch screen can overlap a plurality of simultaneouslydisplayed characters. The touch screen mounted within the body and whichis arranged to display text in an original display configuration withselectable characters that are smaller than an area of user contact withthe screen. The microprocessor, as described above, is in signalcommunication with the touch screen for receiving data indicative of asensed location and area of user contact and for transmitting data tothe touch screen indicative of characters to be displayed on the touchscreen. The microprocessor-run software program is programmed to assessa first area of the touch screen that has been user contacted. The firstarea encompasses a plurality of characters of which at least two havebeen partially covered by the user's contact with the touch screen. Themicroprocessor-run software program can present on the touch screen anexpanded view of the first area that has been expanded to an extent thateach of the at least two partially covered characters is individuallysufficiently large that only one of said at least two characters can bepredominantly covered by similar user contact with the touch screen.Furthermore, the microprocessor-run software program can determine thata first character from the at least two characters that is user selectedin the first expanded view by being predominantly covered by similarcontact with the touch screen in the expanded view. Additionally, themicroprocessor-run software program displays text in the originaldisplay configuration on the touch screen the first character signifiedthat has been determined as being user selected in the first expandedview.

The microprocessor-run software program can be further programmed toassess that a second area of the touch screen has been user contacted,the second area encompassing a plurality of characters of which at leasttwo have been at least partially covered by the area of user contactwith the touch screen. This microprocessor-run software program presentsa second expanded view of the second area that has been expanded to anextent that each of the at least two partially covered characters isindividually sufficiently large that only one of said at least twocharacters can be predominantly covered by the user's contact with thetouch screen on the touch screen. Furthermore, the microprocessor-runsoftware program determines that a second character from the said atleast two characters that is being user selected in the expanded viewbeing predominantly covered by said user contact with the touch screenin said expanded view. Then the microprocessor-run software programcauses the display screen to resume the original display configurationof the text with text between said first character and said secondcharacter being signified as designated text.

In another embodiment, the microprocessor-run software program assessesthat a third area of the touch screen has been user contacted and thatthe area of contact has moved across the touch screen to a thirdlocation where a third area is defined by the user contact, said thirdarea encompassing a plurality of characters of which at least two havebeen at least partially covered by the user's contact with the touchscreen. Furthermore, the microprocessor-run software program can presentan expanded view of the third area upon detection that the user contacthas disengaged from the touch screen and wherein the expanded view hasbeen expanded to an extent that each of the at least two partiallycovered characters in the expanded view is individually sufficientlylarge that only one of said at least two characters can be predominantlycovered by the user's contact with the touch screen on the touch screen.The microprocessor-run software program determines that a thirdcharacter from said at least two characters that is being user selectedin the expanded view by being predominantly covered by user contact withthe touch screen in said expanded view, and inserts the designated textadjacent the third character and resume the original displayconfiguration. Furthermore, this microprocessor-run software program iscapable of executing instructions resulting in the changes discussedabove in relation to FIGS. 1-12.

As intimated hereinabove, one of the more important aspects of thehandheld electronic device 300 to which this disclosure is directed isits size. While some users will grasp the device 300 in both hands, itis intended that a predominance of users will cradle the device 300 inone hand in such a manner that input and control over the device 300 canbe effected using the thumb of the same hand in which the device 300 isheld. However, it is appreciated that additional control can be effectedby using both hands. As a handheld electronic device 300 that is easy tograsp and desirably pocketable, the size of the device 300 must be keptcommensurately small. Of the device's dimensions, limiting its width isimportant for the purpose of assuring cradleability in a user's hand.Moreover, it is preferred that the width of the device 300 be maintainedat less than eight centimeters (approximately three inches). Keeping thedevice 300 within these dimensional limits provides a hand cradleableunit that users prefer for its usability and portability. Limitationswith respect to the height (length) of the device 300 are less stringentwhen considering hand-cradleability. Therefore, in order to gain greatersize, the device 300 can be advantageously configured so that its heightis greater than its width, but still remain easily supported andoperated in one hand.

A potential problem is presented by the small size of the device 300 inthat there is limited exterior surface area for the inclusion of userinput and device output features. This is especially true for the “primereal estate” on the front face 370 of the device 300, where it is mostadvantageous to include a display screen 322 that outputs information tothe user. The display screen 322 is preferably located above a keyboard332 that is utilized for data entry into the device 300 by the user. Ifthe screen 322 is provided below the keyboard 332, a problem occurs inthat viewing the screen 322 is inhibited when the user is inputting datausing the keyboard 332. Therefore it is preferred that the displayscreen 322 be above the input area, thereby solving the problem byassuring that the hands and fingers do not block the view of the screen322 during data entry periods.

To facilitate textual data entry into the device 300, an alphabetickeyboard is provided. In one version, a full alphabetic keyboard isutilized in which there is one letter per alphabetic key. In thisregard, the associated letters can be advantageously organized inQWERTY, QWERTZ, AZERTY, or Dvorak layouts, among others, therebycapitalizing on certain users' familiarity with these special letterorders. In order to stay within the bounds of the limited front surfacearea, however, each of the keys must be commensurately small when, forexample, twenty-six keys must be provided in the instance of the Englishlanguage.

An alternative configuration is to provide a reduced keyboard in whichat least some of the keys have more than one letter associated therewith(see FIG. 1 for an example). This means that fewer keys are requiredwhich makes it possible for those fewer keys to each be larger than inthe instance when a full keyboard is provided on a similarly dimensioneddevice. Some users will prefer the solution of the larger keys over thesmaller ones, but it is necessary that software or hardware solutions beprovided in order to discriminate which of the several associatedletters the user intends based on a particular key actuation, a problemthe full keyboard avoids.

Preferably, the character discrimination is accomplished utilizingdisambiguation software included on the device 300. To accommodatesoftware use on the device 300, a memory 324 and microprocessor 338 areprovided within the body of the handheld unit for receiving, storing,processing, and outputting data during use. Therefore, the problem ofneeding a textual data input means is solved by the provision of eithera full or reduced alphabetic keyboard on the presently disclosedhandheld electronic device 300. It should be further appreciated thatthe keyboard can be alternatively provided on a touch sensitive screenin either a reduced or full format.

As shown in FIG. 1, the handheld electronic device 300 is cradleable inthe palm of a user's hand. The handheld electronic device 300 isprovided with a keyboard 332 to enter text data and place telephonecalls and a display screen 322 for communicating information to theuser. A connect/send key 605 is preferably provided to aid in theplacement of a phone call. Additionally, a disconnect/end key 609 isprovided. The send key 605 and end key 609 preferably can be arranged ina row of keys including a navigation tool. Additionally, the row ofkeys, including the navigation tool, preferably has a menu key 606 and aback key or escape key 608. The menu key 606 is used to bring up a menuon the display screen 322 and the escape key 608 is used to return tothe previous screen or previous menu selection.

The handheld electronic device 300 includes an input portion and anoutput display portion. The output display portion can be a displayscreen 322, such as an LCD or other similar display device.

The keyboard 332 includes a plurality of keys that can be of a physicalnature such as actuable buttons or they can be of a software nature,typically constituted by virtual representations of physical keys on adisplay screen 322 (referred to herein as “virtual keys”). It is alsocontemplated that the user input can be provided as a combination of thetwo types of keys. Each key of the plurality of keys has at least oneactuable action which can be the input of a character, a command or afunction. In this context, “characters” are contemplated to exemplarilyinclude alphabetic letters, language symbols, numbers, punctuation,insignias, icons, pictures, and even a blank space. Input commands andfunctions can include such things as delete, backspace, moving a cursorup, down, left or right, initiating an arithmetic function or command,initiating a command or function specific to an application program orfeature in use, initiating a command or function programmed by the userand other such commands and functions that are well known to thosepersons skilled in the art. Specific keys or other types of inputdevices can be used to navigate through the various applications andfeatures thereof. Further, depending on the application 358 or featurein use, specific keys can be enabled or disabled.

In the case of physical keys, all or a portion of the plurality of keyshave one or more indicia, representing character(s), command(s), and/orfunctions(s), displayed at their top surface and/or on the surface ofthe area adjacent the respective key. In the instance where the indiciaof a key's function is provided adjacent the key, the indicia can beprinted on the device cover beside the key, or in the instance of keyslocated adjacent the display screen 322. Additionally, current indiciafor the key may be temporarily shown nearby the key on the screen 322.

In the case of virtual keys, the indicia for the respective keys areshown on the display screen 322, which in one embodiment is enabled bytouching the display screen 322, for example, with a stylus to generatethe character or activate the indicated command or function. Someexamples of display screens 322 capable of detecting a touch includeresistive, capacitive, projected capacitive, infrared and surfaceacoustic wave (SAW) touchscreens.

Physical and virtual keys can be combined in many different ways asappreciated by those skilled in the art. In one embodiment, physical andvirtual keys are combined such that the plurality of enabled keys for aparticular application or feature of the handheld electronic device 300is shown on the display screen 322 in the same configuration as thephysical keys. Using this configuration, the user can select theappropriate physical key corresponding to what is shown on the displayscreen 322. Thus, the desired character, command or function is obtainedby depressing the physical key corresponding to the character, commandor function displayed at a corresponding position on the display screen322, rather than touching the display screen 322.

The various characters, commands and functions associated with keyboardtyping in general are traditionally arranged using various conventions.The most common of these in the United States, for instance, is theQWERTY keyboard layout. Others include the QWERTZ, AZERTY, and Dvorakkeyboard configurations. The QWERTY keyboard layout is the standardEnglish-language alphabetic key arrangement 44 shown in FIG. 14. TheQWERTZ keyboard layout is normally used in German-speaking regions; thisalphabetic key arrangement 44 is shown in FIG. 15. The AZERTY keyboardlayout 44 is normally used in French-speaking regions and is shown inFIG. 16. The Dvorak keyboard layout was designed to allow typists totype faster; this alphabetic key arrangement 44 is shown in FIG. 17. Inother exemplary embodiments, keyboards having multi-language keyarrangements can be contemplated.

Alphabetic key arrangements are often presented along with numeric keyarrangements. Typically, the numbers 1-9 and 0 are positioned in the rowabove the alphabetic keys 44, as shown in FIG. 14-17. Alternatively, thenumbers share keys with the alphabetic characters, such as the top rowof the QWERTY keyboard. Yet another exemplary numeric key arrangement isshown in FIG. 18, where a “ten-key” style numeric keypad 46 is providedon a separate set of keys that is spaced from the alphabetic/numeric keyarrangement 44. Still further, ten-key numeric arrangements may becommon with or shared with a subset of the alphabetic keys. The ten-keystyled numeric keypad 46 includes the numbers “7”, “8”, “9” arranged ina top row, “4”, “5”, “6” arranged in a second row, “1”, “2”, “3”arranged in a third row, and “0” in a bottom row. Further, a numericphone key arrangement 42 is exemplarily illustrated in FIG. 19.

As shown in FIG. 19, the numeric phone key arrangement 42 may alsoutilize a surface treatment on the surface of the center “5” key. Thissurface treatment is configured such that the top surface of the key isdistinctive from the surface of other keys. Preferably the surfacetreatment is in the form of a raised bump or recessed dimple 43.Alternatively, raised bumps may be positioned on the housing around the“5” key and do not necessarily have to be positioned directly on thekey.

It is desirable for handheld electronic devices 300 to include acombined text-entry keyboard and a telephony keyboard. Examples of suchhandheld electronic devices 300 include mobile stations, cellulartelephones, wireless personal digital assistants (PDAs), two-way pagingdevices, and others. Various keyboards are used with such devices andcan be termed a full keyboard, a reduced keyboard, or phone key pad. Inembodiments of a handheld electronic device 300 having a full keyboard,the alphabetic characters are singly associated with the plurality ofphysical keys. Thus, in an English-language keyboard of thisconfiguration, there are at least 26 keys in the plurality so that thereis one letter per alphabetic key.

FIGS. 19 and 20 both feature numeric keys arranged according to the ITUStandard E. 161 form. In addition, FIG. 20 also incorporates alphabeticcharacters according to the ITU Standard E. 161 layout as well.

As intimated above, in order to further reduce the size of a handheldelectronic device 300 without making the physical keys or virtual keystoo small, some handheld electronic devices 300 use a reduced keyboard,where more than one character/command/function is associated with eachof at least a portion of the plurality of keys. This results in certainkeys being ambiguous since more than one character is represented by orassociated with the key, even though only one of those characters istypically intended by the user when activating the key.

Thus, certain software usually runs on the processor 338 of these typesof handheld electronic devices 300 to determine or predict what letteror word has been intended by the user. Some examples of software includepredictive text routines which typically include a disambiguation engineand/or predictive editor application. The software preferably also hasthe ability to recognize character letter sequences that are common tothe particular language, such as, in the case of English, words endingin “ing.” Such systems can also “learn” the typing style of the usermaking note of frequently used words to increase the predictive aspectof the software. Other types of predictive text computer programs may beutilized with the reduced keyboard arrangements described herein,without limitation. Some specific examples include the multi-tap methodof character selection and “text on nine keys”.

The keys of reduced keyboards are laid out with various arrangements ofcharacters, commands and functions associated therewith. In regards toalphabetic characters, the different keyboard layouts identified aboveare selectively used based on a user's preference and familiarity; forexample, the QWERTY keyboard layout is most often used by Englishspeakers who have become accustomed to the key arrangement.

FIG. 1 shows a handheld electronic device 300 that carries an example ofa reduced keyboard using the QWERTY keyboard layout on a physicalkeyboard array of twenty keys comprising five columns and four rows.Fourteen keys are used for alphabetic characters and ten keys are usedfor numbers. Nine of the ten numbers share a key with alphabeticcharacters. The “space” key and the number “0” share the same key, whichis centered on the device and centered below the remainder of thenumbers on the keyboard 332. While in other embodiments, the number “0”may be located on other keys. Many of the keys have different sizes thanthe other keys, and the rows are non-linear. In particular, the keys inthe middle column 64 are wider than keys in the outer columns 60, 62, 66and 68. To readily identify the phone user interface (the second userinterface), the numeric phone keys 0-9 include a color scheme that isdifferent from that of the remaining keys associated with the QWERTY keyarrangement. In the exemplary embodiment illustrated in FIG. 1, thekeyboard includes a color scheme of the numeric phone keys has a twotone appearance, with the upper portion of the numeric keys being afirst color and the lower portion of the numeric keys being a secondcolor. The first color may be lighter than the second color, or darkerthan the second color.

Another embodiment of a reduced alphabetic keyboard is found on astandard phone keypad 42. Most handheld electronic devices 300 having aphone key pad 42 also typically include alphabetic key arrangementsoverlaying or coinciding with the numeric keys as shown in FIG. 20. Suchalphanumeric phone keypads are used in many, if not most, traditionalhandheld telephony mobile communication devices such as cellularhandsets.

As described above, the International Telecommunications Union (“ITU”)has established phone standards for the arrangement of alphanumerickeys. The standard phone numeric key arrangement shown in FIGS. 19 (noalphabetic letters) and 20 (with alphabetic letters) corresponds to ITUStandard E.161, entitled “Arrangement of Digits, Letters, and Symbols onTelephones and Other Devices That Can Be Used for Gaining Access to aTelephone Network.” This standard is also known as ANSI TI.703-1995/1999and ISO/IEC 9995-8:1994. As shown in FIG. 1, the numeric key arrangementcan be overlaid on a QWERTY arrangement. The numeric arrangement asshown can be aptly described as a top-to-bottom ascending orderthree-by-three-over-zero pattern

While several keyboard layouts have been described above, the layoutscan be described as having keys disposed on the keyboard in a QWERTY,reduced QWERTY, QWERTZ, Dvorak, or AZERTY key layout. These familiarkeyboard layouts allow users to type more intuitively and quickly than,for example, on the standard alphabetic layout on a telephone pad. Asmentioned above, the key arrangements can be reduced compared to astandard layout through the use of more than one letter or character perkey. By utilizing fewer keys, the keys can be made larger and thereforemore convenient to the user.

Exemplary embodiments have been described hereinabove regarding bothhandheld electronic devices, as well as the communication networkswithin which they cooperate. It should be appreciated, however, that afocus of the present disclosure is the enablement of a user of suchwireless handheld electronic devices to select and edit text orcharacters through a touch sensitive screen, which displays an originalconfiguration and an expanded view as needed.
